Harmony Analyisis Help

So I'm new here, and relatively new to harmonic analysis. I was in the process of studying some old hymns, and ran across a chord I simply can't figure out. It has me stumped.

The one that has me stumped is the first beat of the last measure in this selection (which I've uploaded as a pdf). The hymn is obviously in the key of Bb major,and all the other chords are easily identifiable, but what roman numeral should be given to a chord of Eb Bb G and C?

Is the C just a non-chord tone? Any ideas? I feel kind of silly not knowing, since the answer is probably a simple one, but I guess the only way to learn is to ask.

ii6/5 (ii7 in first inversion) would be my analysis.

Yes, it's ii6/5. The tenor's Bb is a suspension, creating a nondominant seventh chord (C Eb G Bb), and is prepared in the previous chord; it resolves to the A.

Awesome! Thanks. That makes perfect sense now. I feel kind of silly for not realizing it to begin with. But thanks guys :)

Well lets see here: 

I would concur.  Since the next chord is IV, pre dom, would have to ii or vi chord. Knowing this, and examing the chorale, the bass note indiactes that it is II chord: A II7. Eb is the third of II chord; hence we have II 6/5,  Not to say that would have use other chords or triads off the same bass note and still conenct to the IV; it would have worked just as well. But here, the chorale picked a this chord for texture and variety. :)

Off topic, much?

It's because you misspelled "as" with two s's, and the filter changed it to "donkey":

it would have worked just donkey well.
